Aquafaba powder, lentil protein and citric acid as egg replacer in gluten-free cake: a model approach.

Food allergies and intolerances have challenged the food industry to create alternatives for allergenic ingredients replacement. Furthermore, meeting vegan diet patterns is even more complicated due to the limited functional properties and sensory characteristics. This study aimed to develop a vegetable powder for egg replacement (VP) for gluten-free cake (GFC) using aquafaba powder (AP), lentil protein (LP), and citric acid (CA) according to a mixture design (MD) with lower and upper restrictions. Three mixtures were chosen based on responses foaming capacity (FC) and foam stability (FS). They were applied as eggs substitute in GFC. The dough physical parameters, proximal composition, microbiological quality, and sensory acceptance of GFC were determined. The AP utilization as raw material in VP is suitable, and mixtures containing 66% to 71.5% of AP, 20% of LP, and 8.5% to 14% of CA were considered suitable for GFC egg replacement. Although the physical characteristics were slightly below...
